Front Panel Key Functionality
The operator can interface with the TTD Annunciator in one of two ways. One is via the Front
Panel keypad. The second way an operator can interface is with the Murphy
Mconfig™ software. This provides the user with a Template displaying the TTD Annunciator setup and status by reading the Modbus registers. Set-up selections can be made and the configuration saved to file for future reference. The software is free and can be downloaded from www.fwmurphy.com
TTD Keypad Features
NOTE: Because the keys have more than one function depending on the operational mode the system is in at the time, the following TTD Keypad
Functionality blocks indicate the keypad action seen if that key is pressed.
The LOW BATT icon can show in any mode if the battery charge is low.
